Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a plastic granule raw material dryer for the production of plastic products. Background Technology

[0002] Plastics are high molecular weight compounds formed by polymerizing monomers through addition or condensation reactions. Their main component is resin, and they also include additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. During the production of plastic products, plastic particles need to be washed. In this process, a large amount of water often remains. If this water is not effectively removed, it will directly affect subsequent processing and product quality.

[0003] A drying device, specifically a plastic granule dryer, is disclosed in Chinese Patent (CN209580166U). It includes a drying cylinder, a fan, and a plastic granule collection cylinder. The fan outlet is connected to the drying cylinder via a pipe equipped with a heater. The drying cylinder outlet is connected to the plastic granule collection cylinder inlet, and the plastic granule collection cylinder outlet is connected to the fan inlet. A granule filter is installed inside the drying cylinder. This invention re-dust-removes the hot air after drying the plastic granules before reheating it in the fan, thus recycling the hot air, saving energy, and preventing a significant increase in factory temperature. Because the hot air does not enter the room, the amount of dust in the factory is significantly reduced. While this novel invention achieves the recycling of hot air and meets environmental protection requirements, it still has problems in drying plastic granules. First, during drying, all the plastic granules pile up together, which reduces the drying effect of the granules piled inside and requires more time to dry. When the drying time is too long, the plastic granules piled on the outside may melt and stick together due to the greater heat they receive. After drying, if the plastic granules are not used immediately, they need to be stored. The freshly dried plastic granules still retain heat, and they need to be cooled before storage, which increases the number of steps and reduces work efficiency. Utility Model Content

[0025] Please see Figure 1-3 The present invention provides the following technical solution:

[0026] A plastic granule raw material dryer for plastic product manufacturing includes a support leg 1, a box body 2 fixedly connected to the upper surface of the support leg 1, a discharge pipe 5 fixedly connected to the bottom of the box body 2, an outlet cover 6 rotatably connected to the lower surface of the discharge pipe 5, and a drying mechanism 4 for drying plastic granule raw materials and a heat dissipation mechanism 3 for dissipating heat from the dried plastic granule raw materials inside the box body 2.

[0027] Among them, the cross-sectional shape of the bottom of box 2 is arc-shaped;

[0028] It should be noted that the discharge pipe 5 is located at the center of the box 2, and the drying mechanism 4 inside the box 2 is located above the heat dissipation mechanism 3.

[0029] The drying mechanism 4 includes heating chambers 404 fixedly connected to the left and right sides inside the chamber 2. Each heating chamber 404 has four heating wires 405 fixedly connected inside. Each heating chamber 404 has an air inlet pipe B402 fixedly connected to its opposite side. Both air inlet pipes B402 penetrate and extend to the outside of the chamber 2. An activated carbon plate B413, a filter screen B414, and a fan B403 are sequentially fixedly connected to the inside of each air inlet pipe B402 away from the chamber 2.

A stirring blade 412 is fixedly connected to the outside of the stirring rod 411 and is located inside the drying box 401. A three-way pipe 408 is fixedly connected to the upper surface of box 2. The bottom end of the three-way pipe 408 extends through box 2 and is rotatably connected to the top end of the stirring rod 411.

[0030] The drying mechanism 4 also includes an electric push rod 415 fixedly connected to the right side wall of the box 2. One end of the output shaft of the electric push rod 415 is fixedly connected to a baffle plate 416. The upper surface of the drying box 401 is also fixedly connected to a feed pipe 407. The top end of the feed pipe 407 passes through and extends to the upper side of the box 2. The bottom of the drying box 401 is also provided with a discharge port 417. The stirring rod 411 is hollow inside and has twenty ventilation holes. All twenty ventilation holes are located inside the drying box 401. There are eight stirring blades 412, which are evenly divided into two groups. Each group has four stirring blades 412 located on the left and right sides of the stirring rod 411.

[0031] It should be noted that the feed pipe 407 is located behind the left air supply pipe 410, and the heating wires 405 are alternately distributed on the left and right sides inside the heating box 404 to increase the air flow path and increase the efficiency of heating the air. The twenty vent holes on the outside of the stirring rod 411 are evenly divided into two groups, located on the front and rear sides of the stirring rod 411 respectively.

[0032] The heat dissipation mechanism 3 includes three inclined plates 305 fixedly connected to the inside of the box 2. Air intake pipes A306 are fixedly connected to both the left and right sides of the box 2. Activated carbon plate A301, filter screen A302, and fan A303 are fixedly connected sequentially inside the air intake pipes A306 away from the box 2. Diverter pipes 304 are fixedly connected to the upper and lower surfaces of the left air intake pipe A306 and the center of the left end of the right air intake pipe A306. The other ends of the three diverter pipes 304 penetrate and extend into the inside of the box 2 and are fixedly connected to the inclined plates 305. Air jets 307 are fixedly connected to the lower surfaces of the three diverter pipes 304, and all air jets 307 are located inside the box 2.

[0033] Among them, the three inclined plates 305 are distributed alternately on the left and right sides inside the box 2, and all the jet heads 307 face the bottom of the box 2;

[0034] It should be noted that a baffle plate is fixedly connected to the left side inside the right intake pipe A306, which can guide the airflow more smoothly into the split pipe 304.

[0035] Working principle: When drying is required, the electric push rod 415 is activated to extend the output shaft, pushing the baffle plate 416 to block the discharge port 417. Then, plastic granules are fed into the feed pipe 407, subsequently falling into the drying chamber 401. The motor 409 is activated, driving the stirring rod 411 to rotate via gear meshing. Then, the heating wires 405 in the two heating chambers 404 are activated for preheating. After preheating, the two fans B403 are activated to filter and activate the air through the filter screen B414. After the carbon plate B413 absorbs impurities, it is sent to the heating chamber 404. The air is heated by the heating wire 405 to form a hot airflow. The hot airflow is then divided into two parts. One part flows into the three-way pipe 408 through the air supply pipe 406, and then flows from the bottom of the three-way pipe 408 into the stirring rod 411, and is sprayed out from the vent on the outside of the stirring rod 411. The other part flows directly into the drying chamber 401 through the air supply pipe 410 for drying. At this time, the stirring blade 412 inside the drying chamber 401 moves with the stirring rod 411. 1. The rotation stirs the plastic granules, allowing them to rotate and preventing accumulation and sticking. The hot airflow from the vent of the stirring rod 411 also dries the plastic granules. After drying, the two fans B403 and motor 409 are turned off, and the two fans A303 are turned on to draw air into the intake pipe A306. After passing through the filter screen A302 and the activated carbon plate A301 to adsorb impurities, the air flows into the three diversion pipes 304 and is then sprayed out from the jet nozzle 307. Then, the electric push rod 415 is activated to retract the output shaft, moving the baffle plate 416 away from the discharge port 417. The plastic granules fall from the discharge port 417 onto the inclined plate 305 and then slide along the inclined plate 305 to increase the distance of fall and allow more time for heat dissipation. During the sliding process, they are also cooled by the airflow from the jet nozzle 307. After all the granules have slid down, the outlet cover 6 is opened, and the plastic granules fall out from the discharge pipe 5 for collection.

[0036] In summary, this plastic granule raw material dryer for plastic product manufacturing, by setting up a drying mechanism 4, uses a heating box 404 and a fan B403 to convert air into hot airflow and deliver it to the drying box 401 to dry the plastic granules. Furthermore, by adding a stirring rod 411 to stir the plastic granules during drying, it prevents the granules from sticking together, reducing drying efficiency, increasing drying time, and preventing large, sticky granules from clogging the discharge port 417. This plastic granule raw material dryer for plastic product manufacturing, by setting up a heat dissipation mechanism 3, can immediately dissipate heat from the plastic granules after drying. By combining these two working steps into one device, it improves overall efficiency and facilitates the subsequent storage of the plastic granules.
